Development and Natural Selection, the Historical Foundations of Mimesis in Animal and Plant Form

In biology, mimesis includes imitation between individuals of the same species – the study object of behavioral sciences and neurophysiology – and mimicry between different species through traits or behaviours generally common to all individuals – to be analyzed from an evolutionary and morphogenetic perspective. Mimicry is widespread among representatives of many animal lineages, but has been also recorded among plants. Mimicry is very often adaptive, e.g. because of protection produced by the similarity of a harmless animal to a poisonous or otherwise dangerous one (Batesian mimicry, e.g., false vs. true coral snakes, or hoverflies vs. wasps), or by sharing of closely similar livery by animals protected by different weapons (Müllerian mimicry). Less conventional kinds of mimicry include the aggressive behaviour of some fireflies imitating the flashing of a different species on which they prey; the intraspecific Müllerian mimicry between larva and adult of some ladybirds; and the presence of identical compounds in the sexual pheromone produced by a female wasp and in the fragrance of the orchid species pollinated by the male. Morphological and biochemical similarity cannot be explained by selective advantage only. Even in cases of adaptive mimicry, shared developmental constraint may facilitate the evolution of similarity between model and mime.In biology, mimesis includes imitation between individuals of the same species – the study object of behavioral sciences and neurophysiology – and mimicry between different species through traits or behaviours generally common to all individuals – to be analyzed from an evolutionary and morphogenetic perspective.

Phylo-evo-devo: combining phylogenetics with evolutionary developmental biology

As a result of the integration of molecular and morphological approaches for the reconstruction of phylogenies, and of the intertwining of developmental and evolutionary biology, further prospects are open for a fruitful interaction between these two fields in what we may call a phylo-evo-devo approach

On two new species of <i>Schendylurus</i> Silvestri 1907 from Venezuela, with redescription of <i>S. colombianus</i> Chamberlin 1921 and <i>S. virgingordae</i> Crabill 1960 (Chilopoda Geophilomorpha Schendylidae)

Two new species of Schendylurus Silvestri 1907 are described, i.e., S. minutus n. sp. from Rancho Grande, Venezuela, and S. paolettii from Boconó, Venezuela. Two further species of the same genus are redescribed, viz., S. colombianus Chamberlin 1921 (after the holotype) and S. virgingordae Crabill 1960 (after a new specimen from the coralline bay Playa Mero, Morrocoy, State of Falcon, Venezuela, which has been compared with the type material). This latter species seems to be halophilous, probably distributed across oceanic spaces by rafting. A key is provided for the identification of the species of Schendylurus of Bolivia, Peru, Ecuador, northern South America, Central America and the West Indies.Facultad de Ciencias Naturales y Muse
